Replaced the right bank 02 just a yr ago, now getting a code for both the right bank o2 and knock sensors. Last time, just replacing the 02 canceled the knock code. What causes and 02 to go so fast and is the knock code, superfluous?

What year is the car? How many miles are on it?

 

97 with 110,000 mi. I was running regular gas, then switched back to 94 not long ago so maybe the shift burnt something. This is the 2nd rt bank 02 in a yr, not even 5000mi.

 

Don't know what to tell ya. Click on search and start searching for 02 problems. Premium gas is better so that is not a problem. Do a visual inspection of the 02 sensor. Perhaps something is causing it to fail. Good luck. Have you done maintenance on it? Spark plugs, cleaning of iacv, etc?

 

Any rust on or around the sensor. I say clean the area, TB, MAF and EGR (if u can). Knock Sensor wouldnt throw 02 sensor. Try some injector cleaner too and no more regular man lol
